For car owners who are familiar with machinery, the most difficult part of replacing the automotive v belt is to adjust the belt tension. The tension should not be too loose or too tight. Whether the belt tension is suitable or not depends on not slipping when dragging a certain torque. Improper maintenance, improper installation due to lack of tools, and worn pulley grooves or worn side belts are all causes of improper tension. Therefore, the following steps should be taken when selecting automobile triangle belts:

(1) Make sure that the car and the fan cannot be started when the belt is replaced.

(2) Loosen the installation lock column and adjusting bolt, and move the generator to remove the old V-belt.

(3) Put the new V-belt on the pulley. Never use a screwdriver or a spudger to pry the belt onto the pulley. Doing so will lose tension and shorten the life of the belt.

(4) After inserting the V-belt into the wheel groove, move the parts of the generator and the generator body that are not easy to pry, and then tighten the adjustment bolt.

(5) Consult the maintenance manual, car manual, and V-belt product instructions, and select the appropriate tension.

(6) Use the tension gauge to accurately measure the tension of the belt. The finger pressure method is not as accurate as the tensiometer. In modern engines, the tension of the belt is relatively high, that is, the belt pulley bears a greater tension, the distance between the belts is shorter, and the belt cross section is less. Therefore, the tension estimated by the feeling is different from the actual tension. Shiatsu is a subjective method of measurement, which varies from person to person. When measuring by finger pressure method, different models have different requirements.

(7) After running the belt for 15 to 20 minutes, make the belt fit the pulley groove, and the tension will be relaxed. Therefore, the belt must be adjusted again.

The models of different brands have different belts because of different engine models. Generally, there are four types of belts: generator belts, air compressor v belt, booster pump belts, and timing belts. The belts of air conditioners and booster pumps of most models are the same, because the number of grooves of air conditioner pulleys and power pump pulleys is the same, and the same type of belt can be used for both. The generator belt is generally a single piece, but it also varies from car to car. There are also many types of generator belt, air conditioning belt, and power steering pump belt that are all in one. There is only one long belt that runs through all the pulleys.

The belt is an important accessory for the normal operation of the engine. Without a belt, there is no transmission of energy. Therefore, when we usually use the car, we must regularly check the wear of the belt. There are grooves on the inner side of the belt, which is also a sign to distinguish the belt model. Generally, it depends on how many grooves the pulley has. For example, if the belt has 5 slots, the belt must be 5PK; if the belt has 6 slots, it must be 6PK. On the front of the belt, there is generally the name of the belt model. We mainly look for the two letters PK. The number in front of P represents the groove number of the pulley, and the number after K represents the length of the belt. If the front number of the original car belt cannot be seen, then the specific belt model can also be determined based on the engine model. Don't worry about this.

Regular inspection of the belt can avoid accidents. When the car is running at high speed, it is still very dangerous for the engine to lose kinetic energy due to the broken belt segment. Usually you can often observe the depth of the belt's clamping groove. If the depth is very shallow, it is easy to cause skidding. Then check the edges of the belt to see if there are any gaps or breaks. Once found, it should be replaced in time.
